AMD Ryzen Threadripper PRO 9955WX vs Intel Core 9 273PTE Comparison

The Verdict

The recorded benchmark data presents an unambiguous hierarchy: the AMD Ryzen Threadripper PRO 9955WX wins all 17 head-to-head comparisons against the Intel Core 9 273PTE. The AMD part is not merely faster; it is faster by margins that range from 32% to 378.7% depending on the workload. The Intel Core 9 273PTE occupies the 82nd percentile of all CPUs in the database, while the Threadripper PRO 9955WX sits at the 97th percentile. The average benchmark score for the AMD processor is 101041, versus 31143 for the Intel part, a gap that places them in entirely different performance classes.

The Intel Core 9 273PTE does have a place in the database, but the data does not support any scenario where it outperforms the Threadripper. Its closest rivals are the Intel Core i7-12700F (0.2% ahead), AMD Ryzen 9 8945HS (0.2% ahead), Intel Core i7-13700TE (0.4% behind), and Intel Core i7-12650HX (0.5% behind). These are mainstream desktop and mobile-class parts. The Threadripper PRO 9955WX, by contrast, trades blows with server-class silicon: it sits 1.2% behind the AMD EPYC 7513, 1.7% ahead of the AMD EPYC 4585PX, 2.2% behind the AMD EPYC 8324P, and 2.6% ahead of the AMD Ryzen Threadripper PRO 5965WX. The data positions the AMD chip in the workstation and server stratum, while the Intel chip belongs to the mid-range desktop tier.

For users whose workloads are bound by single-threaded performance, the AMD part still wins, but the margin narrows to 32% in the PassMark single-thread test. That is the closest contest recorded in the entire comparison. For heavily threaded workloads, the AMD processor is dominant, with multicore Cinebench deltas of roughly 191% across R15, R20, and R23. The PassMark multithread test shows a 178.7% lead. The verdict from the data is simple: the Threadripper PRO 9955WX is the correct choice for any workload where CPU throughput matters, and the Intel Core 9 273PTE is only sensible in contexts where its smaller footprint and lower platform requirements take priority, though the recorded benchmarks do not quantify those aspects.

Architecture Differences

The two processors come from different foundries and process nodes. The AMD Ryzen Threadripper PRO 9955WX is built on a 4 nm process at TSMC, while the Intel Core 9 273PTE uses a 10 nm process at Intel. The AMD chip is based on the Zen 5 architecture with the codename Shimada Peak, and its generation field lists Ryzen Threadripper with Zen 4 (Storm Peak) in parentheses. The Intel chip uses the Bartlett Lake codename and belongs to the Core 9 generation, also Bartlett Lake.

Core counts differ substantially. The AMD part has 16 cores and 32 threads, while the Intel part has 12 cores and 24 threads. The cache hierarchies are structured differently as well. The AMD processor allocates 64 KB of L1 per core and 1 MB of L2 per core, with a 64 MB L3 cache. The Intel processor has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The AMD chip has a larger total L3 footprint, which likely contributes to its advantage in data-heavy workloads.

Memory support is another major architectural divergence. The Threadripper PRO 9955WX supports DDR5 memory across an eight-channel bus with 409.6 GB/s of bandwidth. The Intel Core 9 273PTE supports both DDR4 and DDR5, but only on a dual-channel bus with 89.6 GB/s of bandwidth. That 4.6x difference in memory bandwidth is one of the largest structural gaps between the two parts. Both support ECC memory, which is relevant for workstation and server deployments.

PCIe connectivity also differs. The AMD chip provides Gen 5 with 128 lanes from the CPU alone, while the Intel chip provides Gen 5 with 16 lanes. The Threadripper PRO 9955WX has no integrated graphics, whereas the Intel Core 9 273PTE includes UHD Graphics 730. The AMD part has an unlocked multiplier; the Intel part does not. The production status for both is listed as active, but the AMD part launched on 2025-07-22 and the Intel part on 2026-03-08.

Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX wins every recorded benchmark, so the relevant question is not where each wins, but which workloads show the largest or smallest gaps.

The largest AMD advantage appears in PassMark extended instructions, where it leads by 378.7%. That test measures AVX and similar instruction set throughput, and the magnitude of the lead suggests the Zen 5 core design handles vector workloads far more efficiently than the Bartlett Lake part. The data compression test shows a 256% lead, and random string sorting shows a 244.5% lead. These are memory-bandwidth-sensitive and integer-heavy workloads, where the eight-channel DDR5 configuration and larger L3 cache provide a structural advantage.

The encryption test shows a 211.4% lead for AMD, and the integer math test shows an 186.5% lead. The floating-point math test shows a 157.5% lead. The PassMark multithread test shows a 178.7% lead. In Cinebench R15, R20, and R23, both multicore and singlecore results show roughly 191% leads for AMD, which is consistent across all three versions of the test and indicates a very stable performance ratio between the two parts.

The smallest AMD advantage is in the PassMark single-thread test, where it leads by 32%. The physics test shows a 116.8% lead, and the find prime numbers test shows a 137.3% lead. The Intel part is therefore relatively least disadvantaged in single-threaded integer work, but it still loses by a substantial margin.

The data suggests that the Intel Core 9 273PTE is best suited for scenarios that do not appear in these benchmarks: low-power embedded or edge deployments where its 45 W TDP and integrated graphics matter more than raw throughput. The AMD part, with its 350 W TDP, is clearly positioned for sustained high-performance compute.

Head-to-Head Benchmarks

The head-to-head data shows 17 recorded comparisons, and the AMD Ryzen Threadripper PRO 9955WX wins all of them. The Cinebench suite is remarkably consistent in its verdict. In Cinebench R15 multicore, AMD scores 5996 against Intel's 2060, a 191.1% lead. The singlecore R15 result shows 846 versus 290, a 191.7% lead. Cinebench R20 multicore shows 24987 versus 8586, a 191% lead, and the singlecore result shows 3527 versus 1212, also 191%. Cinebench R23 multicore shows 59494 versus 20445, a 191% lead, while the singlecore result shows 8399 versus 2886, again 191%. The consistency of these deltas across three generations of the Cinebench test suggests a stable architectural performance ratio rather than workload-specific variance.

The PassMark suite provides a wider spread of results. The smallest margin is in the single-thread test, where AMD scores 4530 and Intel scores 3433, a 32% lead. That is the only sub-100% delta in the entire comparison. The physics test shows a 116.8% lead, with AMD scoring 4156 and Intel scoring 1917. The find prime numbers test shows a 137.3% lead, with AMD at 337 and Intel at 142.

The floating-point math test shows AMD at 156215 and Intel at 60673, a 157.5% lead. The integer math test shows AMD at 236120 and Intel at 82411, an 186.5% lead. The multithread test shows AMD at 67035 and Intel at 24054, a 178.7% lead. The data compression test shows AMD at 920954 and Intel at 258704, a 256% lead. The random string sorting test shows AMD at 99813 and Intel at 28973, a 244.5% lead. The data encryption test shows AMD at 44389 and Intel at 14253, a 211.4% lead. The extended instructions test shows the largest gap: AMD at 76363 and Intel at 15952, a 378.7% lead.

What the data implies is that the Intel Core 9 273PTE is most competitive in scalar integer work, where the 32% single-thread deficit is the closest the Intel part gets to parity. The gap widens dramatically as workloads become more parallel, more memory-intensive, or more dependent on wide vector instructions. The eight-channel memory bus and larger L3 cache of the AMD part likely explain the compression, sorting, and encryption results, while the Zen 5 core design explains the extended instructions blowout.
